The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 18274 was prepared by the European Committee for Standardization (CEN) in collaboration with Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee SC 3, Welding consumables, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). Throughout the text of this document, read “...this European Standard...” to mean “...this International Standard...”. It should be noted that, with regard to the corresponding EN standard, the designations given in Clause 9 have been adapted to the needs of international standardization. --```,,,-`-`,,`,,`,`,,`--- iii © ISO 2004 – All rights reserved Copyright International Organization for Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS Not for Resale ISO 18274:2004(E) --```,,,-`-`,,`,,`,`,,`--- Contents page Foreword......................................................................................................................................................................v Introduction ................................................................................................................................................................vi 1 Scope ..............................................................................................................................................................1 2 Normative references ....................................................................................................................................1 3 Classification..................................................................................................................................................1 4 4.1 4.2 Symbols and requirements...........................................................................................................................1 Symbols for the product form ......................................................................................................................1 Symbol for the chemical composition .........................................................................................................2 5 Mechanical properties of the weld metal.....................................................................................................8 6 Chemical analysis..........................................................................................................................................8 7 Retest ..............................................................................................................................................................8 8 Technical delivery conditions.......................................................................................................................8 9 Designation.....................................................................................................................................................8 Annex A (informative) Description of consumable classes..................................................................................10 Annex B (informative) System for designation of welding filler metals ..............................................................16 Annex C (informative) Corresponding national classifications............................................................................17 Bibliography ..............................................................................................................................................................19 iv Copyright International Organization for Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS © ISO 2004 – All rights reserved Not for Resale ISO 18274:2004(E) Foreword This document (EN ISO 18274:2004) has been prepared by Technical Committee CEN/TC 121 “Welding”, the secretariat of which is held by DIN, in collaboration with Technical Committee ISO/TC 44 “Welding and allied processes”. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2004, and conflicting national standards shall be withdrawn at the latest by September 2004. Annexes A, B and C are informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom. --```,,,-`-`,,`,,`,`,,`--- v © ISOfor2004 – All rights reserved Copyright International Organization Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS Not for Resale ISO 18274:2004(E) Introduction --```,,,-`-`,,`,,`,`,,`--- For nickel welding consumables there is no unique relationship between the product form (solid wire, strip or rod) and the welding process used (e.g. gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, strip overlay welding, laser welding or other welding processes). For this reason the solid wire, strip or rod may be classified on the basis of any of the above product forms and can be used as appropriate, for more than one of the above processes. vi Copyright International Organization for Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS © ISO 2004 – All rights reserved Not for Resale ISO 18274:2004(E) 1 Scope This standard specifies requirements for classification of solid wires, strips and rods for fusion welding of nickel and nickel alloys. The classification of the solid wires, strips and rods is based on their chemical composition. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN ISO 544, Welding consumables – Technical delivery conditions for welding filler metals – Type of product, dimensions, tolerances and markings (ISO 544:2003). ISO 31-0:1992, Quantities and units – Part 0: General principles. ISO 14344, Welding and allied processes – Flux and gas shielded electrical welding processes – Procurement guidelines for consumables. 3 Classification The classification is divided into two parts: a) the first part indicates the product form being solid wires, strips or rods, see 4.1; b) the second part gives a numerical symbol indicating the chemical composition of the solid wire, strip or rod, see Table 1. 4 Symbols and requirements 4.1 Symbols for the product form The symbol for the solid wire and rod shall be S and for the solid strip it shall be B. NOTE One product form may be used for more than one welding process. 1 --```,,,-`-`,,`,,`,`,,`--- © ISO 2004 – All rights reserved Copyright International Organization for Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS Not for Resale ISO 18274:2004(E) 4.2 Symbol for the chemical composition The numerical symbol in Table 1 indicates the chemical composition of a solid wire, strip or rod, determined under conditions given in clause 6. The first digit is an indicator of the alloy group as follows: Significant molybdenum addition without significant chromium addition (nickel-molybdenum alloys). 2 No significant alloy addition. 4 Significant copper addition (nickel-copper alloys). 5 Significant copper additions with aluminium and titanium for precipitation hardening. 6 Significant chromium addition, with iron less than 25% (nickel-chromium-iron and nickel-chromiummolybdenum alloys). 7 Same as 6, but with aluminium and titanium for precipitation hardening. 8 Significant chromium addition, with iron more than 25% (nickel-iron-chromium alloys). --```,,,-`-`,,`,,`,`,,`--- 1 The remaining digits indicate the particular alloy deposited. The basis of the system of designation is described in annex B (informative). NOTE In addition the chemical symbol may be used. 2 Copyright International Organization for Standardization Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS © ISO 2004 – All rights reserved Not for Resale Reproduced by IHS under license with ISO No reproduction or networking permitted without license from IHS NiTi3 Chemical NiCu30Mn3Nb NiCu25Al3Ti Ni 4061 Ni 5504 © ISOfor2004 – All rights reserved Copyright International Organization Standardization Not for Resale NiCr20 NiCr20Mn3Nb Ni 6076 Ni 6082 NiCr21Fe18Mo9 NiCr25Fe10AlY NiCr30Fe15Mo5W NiCr30Fe9 NiCr15Fe8Nb Ni 6002 Ni 6025 Ni 6030 Ni 6052 Ni 6062 1,0 Mn 0,25 0,15 1,0 0,08 0,04 0,03 0,15 to 0,25 0,05 to 0,15 1,0 1,0 1,5 0,5 2,0 0,10 2,5 to 3,5 0,08 to 0,25 0,20 1,5 4,0 0,15 2,0 to 4,0 0,15 C 0,01 to 0,10 NICKEL – CHROMIUM – IRON NiCr44Ti Ni 6072 NICKEL – CHROMIUM NiCu30Mn3Ti Ni 4060 NICKEL – COPPER Ni 2061 NICKEL Numerical Alloy symbols 6,0 to 10,0 7,0 to 11,0 13,0 to 17,0 8,0 to 11,0 17,0 to 20,0 3,0 2,00 0,50 2,0 2,5 2,5 1,0 Fe 0,3 0,5 0,8 0,5 1,0 0,5 0,30 0,20 1,0 1,25 1,2 0,7 Si c 0,5 0,3 – – – – – – – Co c Min. 59,0 Min. 70,0 Min. 54,0 – – 5,0 – Min. 44,0 0,5 to 2,5 Min. 67,0 Min. 75,0 Min. 52,0 63,0 to 70,0 Min. 60,0 Min. 62,0 Min. 92,0 Ni 1,0 to 2,4 Min. 36,0 0,1 0,5 0,5 0,50 0,50 Min. 20,0 28,0 to 32,0 28,0 to 32,0 0,2 Cu – 1,1 – 1,8 to 2,4 – – 0,4 – 2,0 to 4,0 1,0 1,2 1,5 Al – 1,0 – 0,1 to 0,2 – 0,7 0,5 0,3 to 1,0 0,3 to 1,0 1,0 1,5 to 3,0 2,0 to 3,5 Ti – – – – Cr a b d – – – 3,0 – – Nb – – 0,10 14,0 to 1,5 to 17,0 3,0 28,0 to 31,5 28,0 to 0,3 to 31,5 1,5 24,0 to 26,0 20,5 to 23,0 18,0 to 2,0 to 22,0 3,0 19,0 to 21,0 42,0 to 46,0 Chemical composition in % (m/m) – 0,5 4,0 to 6,0 – 8,0 to 10,0 – – – – – – – Mo Table 1 — Symbols and chemical composition requirements for solid wires, strips and rods – – 1,5 to 4,0 – 0,2 to 1,0 – – – – – – – W ef – Al + Ti < 1,5 – Zr 0,01 to 0,10 Y 0,05 to 0,12;
